利用压汞毛管压力曲线求得的微观均质系数α,是表征储层孔隙结构均质程度和影响水驱油效率的主要特征参数之一。比较某些孔隙结构的特征参数与水驱油效率有更好的线性关系。并说明在一定条件下,储层孔隙结构对水驱油效率的影响主要是均质程度。本文建立了均质系数α的数学表达式,以及它与亲油、亲水岩样水驱油效率的统计关系式,应用α与水驱油效率关系等图版,预测了几个油田岩样的水驱油效率,结果与实际比较符合。
The microscopic homogenization coefficient α obtained from the capillary pressure curve of mercury injection is one of the main characteristic parameters that characterize the degree of homogeneity of pore structure and the efficiency of water flooding. Comparing the characteristic parameters of some pore structures with the water flooding efficiency has a better linear relationship. The results show that under certain conditions, the effect of reservoir pore structure on water flooding efficiency is mainly homogeneous. In this paper, the mathematical expression of the homogenization coefficient α and its statistical relationship with the water flooding efficiency of lipophilic and hydrophilic rock samples were established. By using the plates such as the relationship between α and water flooding efficiency, Water flooding efficiency, the result is more in line with the actual.
